Hi,
have you solved the problem? We have the same problem with QuickTime. We have tied to render via AFP and SMB to the network shared drive which is formatted in HFS+ and encountered the same problem. After this we formatted network drive to exFAT and render completed successfully, so it seems that Davinci has the problem with HFS+ network shared drives.
Would be great to heat how you solved your problem.
Regards,
Linas
